To search for a repeater’s sub-audible tone frequency,
a tone scan is available.
By monitoring a repeater signal with a tone squelch or
DTCS, you can determine the tone frequency neces-
sary to open the repeater or the squelch.
q
In the FM mode, push [MENU] to display the “M1”
screen (Menu 1).
w
Hold down [TON](F-4) for 1 second to enter the
“TON” screen.
e
Push [TON](F-1) one or more times to select the
tone type to be scanned.
• “Rptr Tone” for a repeater tone, “TSQL Tone” for tone
squelch or “DTCS Code” for a DTCS code can be se-
lected.
• When selecting a DTCS code to be scanned, the DTCS
code and its polarity is displayed. You can select the de
-
sired polarity by pushing [F-5].
“NN” : Normal polarity for both transmit and receive.
“NR” : Normal polarity for transmit and reverse polarity
for receive.
“RN” : Reverse polarity for transmit and normal polarity
for receive.
“RR” : Reverse polarity for both transmit and receive.
r
Push [SCAN](F-2) to start the Tone scan.
• “Rptr Tone SCAN,” “TSQL Tone SCAN” or “DTCS Code
SCAN” blinks, depending on the type you selected.
• If
“Up/Down” is selected as the “MAIN DIAL (SCAN)”
option in the Scan Set mode, rotating [MAIN DIAL]
changes the scanning direction. (p. 147)
t
When a matched tone or code is found, the scan
pauses, and the detected sub-audible tone fre-
quency or DTCS code is set.
• Hold down [F-3] for 1 second to reset to the default set
-
ting, if desired.
y
Push [SCAN](F-2) to cancel the Tone scan.
When the tone scan or DTCS code scan is used in
the Memory or Call channel mode, the detected
tone frequency or code can be used temporarily.
To save the detected tone frequency or code set-
ting, you must over-write the Memory or Call chan-
nel data. (pp. 140, 141)
